Abstract: The home pregnancy testworks by measuring human chorionic gonadotropin (hCG) hormone in urine. This hormone was initially studied in NICHD intramural laboratories as a reliable marker of certain tumors. Refinement of the assay for hCG detection to enhance specificity enabled its ready application to pregnancy detection. 

Evaluation of a Plasma hCG Method for Point of Care Testing with the Aim of Shortening Test-Turnaround-Times

It is suggested that the i-STAT® hCG blood assay could be used as a complement to urine hCG assays in clinical situations when rapid test results are needed and urine is not available.

Comparison of accuracy and certainty of results of six home pregnancy tests available over-the-counter

The Clearblue Digital Pregnancy Test (CBDPT) was significantly better in terms of accuracy and certainty than non-digital OTC HPTs tested at a low hCG concentration and demonstrates that a digital reading offers significant benefits to the consumer over traditional non- digital tests.

The long gestation of the modern home pregnancy test.

The ability of women to confirm their pregnancies in the privacy of their own homes was described as a “private little revolution” 35 years ago, when the early version of the modern home pregnancy

Maternal Responsibility and Traceable Loss: medicine and miscarriage in twentieth-century Australia

The meaning of miscarriage in twentieth century Australia is historicised and a number of crucial turning points in scientific interpretations of the causes and treatments of miscarriage that produced shifts in the communication of responsibility to women for their own pregnancy losses are identified.

Comparison of volunteers' experience of using, and accuracy of reading, different types of home pregnancy test formats.

In this study, the branded midstream digital test was superior to other tests evaluated and fulfilled the criteria of being an easy-to-use and interpret test; strip and cassette tests showed poor performance in women's hands.

Human Plasma Proteome During Normal Pregnancy.

The results suggested that the plasma proteome may provide a non-invasive readout of placental cellular dynamics and serve as a blueprint for investigating obstetrical disease.



Appearance of hCG in pregnancy plasma following the initiation of implantation of the blastocyst.

Results indicate that hCG does not appear in the maternal circulation until after the initiation of implantation of the blastocyst, and that the first significant rise in plasma hCG occurred 9 to 13 days after ovulation.

Patients with tumors of the stomach, liver, ovary and testis were found to have the highest incidence of ectopic hCG secretion.

The absolute amount of hCG and hCGα decreased after the first trimester but the relative quantity of h CGα exceeded that for immunoreactive hCG by more than 10-fold in the last two trimesters.

Evidence for altered synthesis of human chorionic gonadotropin in gestational trophoblastic tumors.

The most striking finding was the absence of free circulating hCGalpha in the sera in patients with gestational trophoblastic disease which responded to chemotherapy, since free hC Galpha is readily detectable in theSera of normally pregnant women.

Immunologic and physical characterization of human chorionic gonadotropin (hCG) secreted by tumors.

Qualitative and quantitative differences of hCG and its subunits extracted from the primary tumor and its metastases suggest that in vivo cloning of tumor cells may occur.

Editorial: When is a tumor marker not a tumor marker?

Almost all the biologically active protein and polypeptide hormones, including those synthesized and secreted by the normal placenta, have been implicated in ectopic humoral syndromes associated wi...

Specific radioimmunoassay of chorionic gonadotropin during implantation in rhesus monkeys.

These findings demonstrate that the attaching blastocyst or the developing syncytiotrophoblast either already possesses or rapidly attains the capacity to secrete mCG.

Hormonal factors influencing ovarian uptake of human chorionic gonadotropin.

The ovarian uptake of tritiated human chorionic gonadotropin (3H—hCG) in hypophysectomized rats was investigated and correlated with ovarian morphology after treatment with various combinations of
